[Qemu-devel] [PATCH] Fix another corner-case of using VNC+SASL+SPICE

[Qemu-devel] [PATCH] Fix another corner-case of using VNC+SASL+SPICE

[Christophe Fergeau]

Similarly to the previous commit fixing VNC+SASL+QXL, when starting
QEMU with SPICE but no SASL, and also VNC with SASL, then
spice_server_init() will get called without a previous call to
spice_server_set_sasl_appname(), which will cause cyrus-sasl to
try to use /etc/sasl2/spice.conf (spice-server uses "spice" as its
default appname) rather than the expected /etc/sasl2/qemu.conf.

This commit unconditionnally calls spice_server_set_sasl_appname()
before calling spice_server_init() in order to use the correct appname
even if SPICE without SASL was requested on qemu command line.
